<h3>NAME</h3>
processlist_states: Summary of processlist states and their run time
<h3>TYPE</h3>
View

<h3>DESCRIPTION</h3>
<p></p>

<p>
	<i>processlist_states</i> aggregates the various <a href="http://dev.mysql.com/doc/refman/5.1/en/general-thread-states.html">thread states</a> 
	and presents time metrics for those states. 
</p>

<p>
	It makes for a general overview of "what is my MySQL server doing right now".	
</p>
